In the field of electrical engineering, the transformer plays a central role. Invisible to most users, it is nonetheless essential to the proper functioning of electrical installations, whether…
When it comes to ignition transformers, experience matters: insulation quality, durability over time, product compatibility… MONTELEM Industrie, formerly based in Arcueil, developed this expertise…
We are pleased to present our new website. It has been entirely redesigned to offer you a simpler, smoother and more efficient experience. This new…
Since 1 July 2021, a major milestone was reached for transformer manufacturers and users in Europe with the entry into force of Phase 2 (or "…
In many industrial, technical or sensitive environments, the power supply must be reliable, stable and safe. The isolation transformer meets precisely these requirements. Often discreet within a…
What actually happens when you switch on a transformer. At the precise moment of energising, the transformer can draw a brief but very high current. This peak, perfectly normal, lasts only…
Unlike the invention of the transformer itself—which is often attributed to pioneers such as Faraday or Zipernowsky, Bláthy, and Déri—the electrostatic screen is not the work of a single inventor. It is…
In the field of electricity, systems are classified according to their voltage level: Low Voltage (LV), Medium Voltage (MV), and High Voltage (HV). These categories aren't arbitrary…
In many industrial, technical, or sensitive environments, the power supply must be reliable, stable, and safe. The isolation transformer meets these requirements precisely. Often unobtrusive within a system, it…
